“We’ve had enough Bushes,” said no less than Barbara Bush, the family matriarch, when asked in 2013 if son Jeb should run for president. She was right then, but she’s recently changed her tune. “When the idea of Jeb running for President first came up, I was hesitant,” Mrs. Bush wrote in a letter to supporters. “You may have heard about that. When you see the pounding candidates, their spouses, and even their children take, what mother wouldn’t be? But our problems are so profound that America needs a leader who can renew the promise of this great nation.” Indeed, but there are more than 300 million Americans without the surname “Bush,” and several qualified Republicans are ready to join the presidential field. But never mind that, she says: “Jeb is our best chance of taking back the White House in 2016, and I hope that you will join me in pushing him to run.” It certainly does appear he’s running, but, again, “We’ve had enough Bushes.”
